PAPER-FEEDER.

SPECIFICATION forming part of Letters Patent No. 391,087, dated October 16, 1888.

Application filed June 9, 1887. Serial No. 240,727.

To @ZZ whom it may concern.:

Be it known that we, ALONZO SEDGWIOK and WILLIAM WoMEnsLEY, both of the city ofPoughkeepsie, in the county of Dutchess and State of New York, and RALPH J. BROWN, of the city, county, and State of New York, have invented a new and useful Improvement in Paper-Feeders, of which the following isaspecication. r3 This invention relates to that class of paperfeeders by which sheets are successively fed from a pile to a printing-press, ruling-niaehine, or other machine in which the sheets are operated upon.

The object of this invention is to provide means by which the sheets are placed in correct register laterally, which is of great iniportance, especially when feeding to a printing-press.

2o Heretofore ithas been very difficult to feed sheets to printing-presses by automatic feeders in such manner that the printing on both sides of the sheet would be in correct register back to back, and a large percentage of waste was occasioned by the incorrect register of the sheets.

The object of our invention is to overcome these difliculties; and it consists of the iniprovements which will be hereinafter fully de- 3c scribed, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is a vertical section of a paper-feeder provided with our improvements, the section being taken in the direction of the feed movement. Fig. 2 is a longitudinal section, on an enlarged scale, of one of the side fingers and connecting parts. Fig. 3 is a top plan view thereof. Figs. 4 and 5 are crosssections in lines x a: and y y, Fig. 2. Fig. 6 is 4o a sectional elevation showing the side ringer raised preparatory to grasping the sheet. Fig. 7 is a longitudinal section ofthe side guide with which the side finger is connected. Fig. 8 is a bottom plan view of the mechanism by which the side fingers on both sides of the fced-b0ard are connected.

Like letters of reference refer to like parts in the several gures.

A represents the main feed-board, which (No model.)

may be the feed-board of a printing-press to which the paper' is fed, as indicated in the drawings.

c represents the cylinder of a printing-press to which the sheets are fed, and a representsr one of the usual front guides with which the press is provided and against which the sheets are fed.

B represents an auxiliary feed-board placed upon the lower portion of the main feed-board A; and b represents the lower feed tapes, whereby the sheets are carried upon the auX- iliary feed-board B, the lower tape-roller, b', being preferably so arranged that the upper edge of the sheet has cleared the lower tapes when the lower edge rests against the front guides, c'.

1fl represents the upper feed-tapes, which may be of any suitable construction.

The sheets are fed successively from a pile upon the auxiliary feedboard B by any suit- 7o able automatic feeding mechanism. The construction of such feeding mechanism forms no part of this invention, and it may be of any suitable kind-for instance, that described and shown in an application for patent filed by A. Sedgwick, October 23, 1886, Serial No. 217,0012.

C represents a laterally-movable clamping` finger arranged on the auxiliary feed-board B so as to seize each sheet near its lateral edge 8c and move it laterally on the feed-board to the point of register. The linger O has the form of an elbow-lever, and is composed of an up per arm, c, standing horizontally, or nearly so, in its normal position, and a depending arm, c. The finger is pivoted at the junction of its two arms by a horizontal bolt, d, to two ears, d', between which the finger is arranged, and which are formed on the upper side of a slide, D. The long arm c of the finger C is provided near its end with a head, c2, of rubber, leather, or other suitable material, which will enable the finger to take a firm hold on the paper.

E E represent upright side guides secured to the slide D on both sides of the long arm c of the finger C and forming a rest or stop for the lateral edge of the sheet.

e e represent curved guides, which are seward extension, e2, which assists in guiding` v board is not obstructed between the clamping cured to the inner sides of the side guides, E E', and which project inwardly and upwardly therefrom, so as to guide the lateral edges of the sheets downwardly against the side guides at their point of junction with the slide D. The curved guide e is provided with an upthe sheets under the tiijger C. The depending arm c of the finger C projects downwardly through an opening, f, in the slide D, which opening limits the oscillating movement of the nger on its pivot. The arm 'c' is bifurcated below the slide D and straddles a sleeve, G, which is adj ustably secured to a horizontal rod, g, arranged on the under side of the aux*- iliary feed-board B and guided in bearings g g2, attached to the same. The sleeve G is provided with collars g3 g4, between which the bifurcated arm c is arranged.

H represents a slotted guideplate on which the slide D moves inwardly and outwardly, and which is arranged transversely on the feedboard. This plate H is in turn supported on a slotted plate, I, which is secured in an opening, t', formed in the auxiliary feed-board near the side thereof. The guide-plate H is secured to the plate I by screws h or other means, which permit the plate H to be adjusted on the plate I inwardly and outwardly, as may be required, to place the plate H in the proper position for registering the sheets. The slide D is held in place on the slotted plate H by a transverse spring, j, which is secured to astud, j', on the under side of the slide, and which bears against the under side of the plate H, as represented in Fig. 4.

The upper surfaces of the slide D and the plates I and H are flush with the upper surface of the auxiliary feed-board, so that the sheets can pass freely over these parts, the plate H forming a recessed way in the feed# board, in which the slide D moves.

By locating the actuating mechanism underneath the slides to which the clampingingers are attached the space above the feedfingers, and the upper carrying-tapes can be readily extended to the extremity of the feedboard.

A clamp-iinger, C, is required on one side of the feed-board only; but in order to enable the sheets to be registered against either side of the feed-board, as circumstances may require, provision is made for operating the clamping-finger on either Vside of the board. To this end an actuating-rod, 7c, is arranged on the opposite side of the feed-board in line with the rod g, and the feed-board is provided adjacent to the rod 7c with an opening, 7c', sup- 'porting-plate k2, slotted plate 7c3, sleeve la, and` aclamping-tinger corresponding with the si mi lar parts on the opposite side of the vfeedboard. The rods g and 7c are connected by a lever, Z, and rods Z Z2 and an arm, Z3, as represented in Fig. 8. .The arm Za is secured to the rod k and a parallel rod, m, which slides in bearings m m, and is provided with a spring,

n, resting against the bearing m', and acollar, n', on the rod m. This spring tends to hold the rods g and k in their innermost position.

o represents a pulley attached'to the under side of the auxiliary feedlboard B, and o is a cord or chain running around said pulley and attached with one end to therod m and with its other end to a rod,p, which extends upwardly over the main feed-board and connects with the lower arm, p', of an elbow lever, P, the upper arm, p", of which rests upon a cam, Q. The latter is secured to a horizontal shaft, q, which makes one revolution for every sheet of paper which is fed forward. This cam is provided with a deep depression,r, a raised projection, r', in rear of the deep depression; and a concentric face, r2, extending arourn'd thegreater part of the cam, slightly below the projection r'.

When the lever P rest-s upon the projection r' of the cam Q, the rodsg` and 'la are in their outermost positions, and the clamping-finger C, connected with either of said rods, stands in its outermost position. This position of the clamping-nger and of the slide D, to which it is attached, determines the outermost position of the side guides, E E', secured to the slide D. The outermost position of these side guides is the point to which the lateral edge of the sheet is required to be moved in order to bring it incorrect lateral register; hence, in adjusting the slotted plate H on itssupporting-plate I and the collar G. on the rod g these parts are so adj usted that when the slide D is in its outermost position the side guides, E, coincide with the line on which the lateral edges of the sheets must be placed in order to be in correct register. The cam revolves in the direction of the arrow in Fig. 1. Vhen the lever P drops into the deep recess r of the cam, the rodg moves quickly inward under the pressure of the spring` n and carries the slide D with it, the linger() being elevated, as represented in Fig. 6, and moving the slide by contact of its lower arm, c?, against the inner end of the openingf. The extent of this inward movement of the slide is such as to bring the lateral edges of the sheets in contact with the side guides, E E', under the usual variations with which the sheets pass over the feed-board.

In Fig. 7 s s s represent three different positions of sheets passing over the feed-A board, in each of which the side guides, E E', strike the lateral edge of the sheet before the side guides reach the inner limit of this movement, which is indicated by dotted lines. As soon as the side guides strike the edge of thesheet the latter is pushed back by the side guides until the side guides reach the inner limit of their movement. The lever P now rises out of the deep recess r and draws the rod g rapidly outward, thereby lcompressing the spring n. The rst part of the outward movement of the rod g causes the finger C to be turned on its pivot, so as to bring the head c IIO down on the sheet,which latter is thus firmly clamped between the finger C and the slide D, the edge of the sheet resting against the side guides, E E. \Vhen the finger has clamped the sheet, the continued outward movement of the rod g causes the slide D to be moved outwardly until the outer limit of the movement is reached,which is'the ease when the leverP rests against the projection r of the cam Q. Immediately after the slide has reached this position the lever P drops upon the concentric face r2 of the cam, which permits the rod g to move inwardly under the pressure of the spring far enough to raise the finger from the sheet without disturbing the position of the slide D. lThe sheet so released is seized by the nippers of the press and drawn away. rIhe lever P now rests upon the concentric face r2 of the cam Q, and holds the slide in its outermost position until the next inward movement takes place.

The clamping-finger which is not required for use can be removed with its supportingslide from the feed-board. By this means each sheet is firmly seized and brought to the same line laterally, thereby insuring a correct side register of the sheets and enabling the sheets to be fed with certainty to a printing-press or other machine which requires a correct register of the sheets.

XVe claim as our invention- 1. The eombination,with the feed-board, of a transversely-moving slide,a clamping-finger pivoted to said slide, and an actuating-rod connected with the clamping-1iger, whereby the slide is moved by the actuating-rod through the medium of the clamping-finger, substantially as set forth.
